In a bowl add all flours and salt; mix well. Add butter milk and water, mix well without lumps. Batter should be thinner than the regular dosai batter consistency
Add all the other ingredients listed except oil and combine well. Keep the batter aside for 10 - 15 minutes
In medium flame, heat a non stick/ iron dosai pan. Check for the batter consistency if it has become thick drizzle 1/2 tablespoon of water
Once the pan becomes hot, take a ladle full of batter and make a outer circle, because the batter is thin it will be spread in the middle. If required fill small portion of batter in between. Drizzle oil and cook on side, after it is cooked carefully flip the other side. Instant wheat dosa is ready, serve it with chutney/sambar/thokku
